The Timing Shift Box (TSB) is an accessory that has been available for the ARRICAM already, and is now also available in a version compatible with the 435 Advanced and 435 Xtreme.

The Timing Shift Box alters the phase relationship of the mirror shutter to the movement, so that the film is exposed while being transported. This creates a streaking effect that has become popular to indicate a heightened awareness of the characters, like in a combat situation, for instance, or an unusually stressful or unique state of mind. Even though a timing shift was considered an image defect for decades, modern film cameras like the ARRICAM Studio, ARRICAM Lite or 435 can now make this effect available to film makers in a controlled fashion.

With the TSB the timing shift effect can be adjusted from very faint to very strong, and the amount of jitter, a random fluctuation in the strength of the effect, can also be set to various degrees. In the past a timing shift effect with jitter used to be done by purposefully misadjusting the timing belt of the oldest camera in the fleet; this effect can now be simulated by the software that controls the camera movement and mirror shutter motors. The timing shift effect can be executed while the camera is running (a timing shift ramp), or the effect can be locked to remain constant.

The 435 Timing Shift Box is connected to the 435 by means of the MCB Cable Adapter and the 435 Timing Shift Box Cable. To distinguish the 435 Timing Shift Box from the ARRICAM Manual Control Box (black cover) and from the ARRICAM Timing Shift Box (red cover), the 435 Timing Shift Box has a blue front cover.
